Deployable Systems

These deployable systems are part of NSF-s Lower Atmospheric Observing Facilities (LAOF) and are requestable to all qualified scientists requiring facilities and services to carry out their research objectives.

Surface and Tower Measurements with the Integrated Surface Flux System (ISFS)

ISFS can be deployed as a widely distributed network of surface weather stations - measuring the surface energy budget, fluxes, and some soil paramteres. Alternatively, it can be deployed in closely spaced arrays to support intensive micrometeorological research at a single site. Solar power, RF modems and satellite data transmission permit ISFS to operate almost anywhere.

Stationary and Mobile Radiosonde Systems with the GPS Advance Upper-Air Sounding system (GAUS/MGAUS)

GAUS is a balloon-borne rawinsonde sounding system that uses GPS technology to measure high vertical resolution of temperature, humidity and winds at locations around the world.

Stationary and Mobile Atmospheric Profiling with the Integrated Sounding System (ISS/MISS) and Multiple Antenna Profiling Radar (MAPR)

The ISS combines surface, sounding, and remote sensing instrumentation to provide a comprehensive description of lower atmospheric thermodynamics and winds.
Integrated instruments are:
  • a 915 MHz Doppler wind profiling radar (with RASS for temperature profiling)
  • a GAUS radiosonde system
  • an enhanced surface meteorological station (radiation and precipitation data in addition to standard temperature, pressure, humidity and wind)
  • Local data processing, display, and communications infrastructure
  • ISF can deploy a network of 3 ISS stations; a mobile version (Mobile ISS); a high-resolution version (MAPR), and separate GAUS and Mobile GAUS radiosonde stations.
ISS, MISS and MAPR Sites

Dropsondes Released from Aircraft using the Airborne Vertical Atmospheric Profiling System (AVAPS).

The NCAR GPS Dropsonde System, also known as AVAPS, provides detailed profiles of atmospheric temperature, humidity, pressure, and horizontal wind from locations targeted with aircraft. Systems are available on the NCAR aircraft (NSF/NCAR GV and C-130) as well as many research aircraft used world-wide.
